Do the OH groups want to be furthest apart? or the CH3 groups?
I'm trying to determine the lowest energy conformation - and I don't know which group has the bigger steric effect?

I presume it is in the gauche form that its energy is minimun because of possible hydrogen bonding between the hydroxy groups

In butan-2-ol you have one alcohol, which is indeed smaller than the methyl group.
